Book excerpt: The varying cancer incidence from country to country and region to region suggests that en vironmental factors play a considerable role in the aetiology of cancer. Whether these factors in the environment moderate the effect of car cinogenic chemicals or whether they might them selves be carcinogenic is not known at the present time. What is known is that there are various chemicals, both naturally occurring and man-made, which can induce cancer in man. In the Western world estimates vary as to how much cancer is occupational in origin; the figures range from 1% to 40%. It is our feeling that probably about 10% of cancer has a direct oc cupational origin. Nevertheless this number is considerable and it behoves us therefore to identify those chemicals which are carcinogenic and to reduce human exposure. Recent work on the mode of action of carcinogenic chemicals suggests that the majority exert their effect through an activation step to give elec trophilic metabolites. Such metabolites have as a common feature the ability to react with cel lular nucleophiles to give covalently bound products. Such reaction will occur after carcino gen treatment of animals with nucleic acids par ticularly in target organs. It is reaction with nucleic acids that provides the basis of a num ber of short-term tests for carcinogens, since the basic composition of DNA is similar in micro-organisms and in human cells.

Book excerpt: Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.

Available in PDF, EPUB and Kindle. Book excerpt: The scientific basis, inference assumptions, regulatory uses, and research needs in risk assessment are considered in this two-part volume. The first part, Use of Maximum Tolerated Dose in Animal Bioassays for Carcinogenicity, focuses on whether the maximum tolerated dose should continue to be used in carcinogenesis bioassays. The committee considers several options for modifying current bioassay procedures. The second part, Two-Stage Models of Carcinogenesis, stems from efforts to identify improved means of cancer risk assessment that have resulted in the development of a mathematical dose-response model based on a paradigm for the biologic phenomena thought to be associated with carcinogenesis.

Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book excerpt: In the rapidly developing field of environmental mutagenesis, the use of stand­ ardized protocols has permitted the evaluation of large numbers of chemicals for mutagenic and potential carcinogenic activity. In this sixth volume of Chemical Mutagens, the chapters by Perry, Williams, Rosenkranz and Leifer, Kada et al., Pienta, Tazima, Epler, and Rinkus and Legator provide a systematic listing of the chemicals that have been tested, bringing together both unpublished and previously published data. These chapters will serve as an important milestone by providing a convenient reference to tabulated test data with particular assay systems. Another important area of research is the modification of mutagenic activity. In the chapter by Sugimura and Nagao, factors that alter in vitro metabolic activation are discussed, whereas in the chapter by Maher and McCormick, the role of genetic heterogeneity is considered. Equally important is our need to obtain a better understanding of mutation-induction kinetics, and the mathematical analysis by Haynes and Eckardt provides an important step in this direction. An important new approach for the induction of specific locus mutations in human cells in culture is discussed in the chapter by Thilly and co-workers. We have also been concerned about the problems in the practical applica­ tion of various short-term tests in commerical testing laboratories. The prob­ lems emerging in the evaluation of potentially important new chemicals have been discussed in a chapter by Brusick et al.

Available in PDF, EPUB and Kindle. Book excerpt: This volume will provide a contemporary account of advances in chemical carcinogenesis. It will promote the view that it is chemical alteration of the DNA that is a route cause of many cancers. The multi-stage model of chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action will be a focal point. The balance between metabolic activation to form biological reactive intermediates and their detoxification, ensuing DNA-lesions and their repair will be profiled. It will describe the chemical changes that occur in DNA that result from endogenous insults including epigenetic changes that lead to gene silencing. It will describe major mechanisms of mutagenesis, affects on tumor suppressor genes and proto-oncogenes, and how cell-cycle check points can be by-passed by the "stealth-like" properties of chemical carcinogens. Environmental agents that can promote tumor formation will be discussed. The monograph will have wide appeal as a knowledge base for graduate students, post-doctoral fellows and faculty interested in this aspect of cancer causation and research.

Available in PDF, EPUB and Kindle. Book excerpt: Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.

Available in PDF, EPUB and Kindle. Book excerpt: During the early 1930s, when I was a graduate student and later a post-doctoral researcher at the National Research Council for the University of Wisconsin at Madison, we had the opportunity to get acquainted with many graduate students from China who were sent to the University for training in modern basic sciences as well as social sciences. The University of Wisconsin continues to graduate a large number of Chinese students. Economic conditions in the 1930s were very precarious for the United States and other parts of the world. Many of us students grew closer together because we were living on similarly tight budgets. As a matter of fact, we subleased a part of our apartment in Madison to some Chinese graduate students. This was a very nice opportunity for us to learn about the scientific and cultural back ground of our Chinese friends. Many of them came from the interior of China and had had very little opportunity to become acquainted with people from a western culture. Living with these students was a very pleasant and educational experience which gave us a good pic ture of the cultural life and educational system of China at that time--an intimate picture that one normally would not see without travelling in that country.

Book excerpt: These two volumes contain the papers presented at a North Atlantic Treaty Organization (NATO) Advanced Study Institute held on September 22-28, 1979 in Monte Carlo, Monaco. The conference was entitled "In Vitro Toxicity Testing of Environmental Agents: Current and Future Possibilities." This international conference presented an opportunity for the participants to exchange informa tion and ideas on the current approaches (both scientific and po litical) for toxic assessment of environmental agents. The poten tial health effects of these compounds as well as future needs in the environmental research field were discussed. The scientific content of the conference seminars included an overview of the various cellular, subcellular, organ, animal, and genetic systems which have been used to assess the health effects of environmental agents. The scientific principles behind short term assays and an evaluation of their applicability to health effects monitoring and analysis were investigated. Included among major topics were: (1) the biochemistry and pharmacology of selected environmental agents; (2) molecular mechanisms of car cinogenesis, mutagenesis, and transformation; (3) bacterial muta genesis and toxicity; (4) mammalian cell mutagenesis, toxicity, and transformation; (5) in vitro carcinogens and mutagens; (6) teratogenic and other developmental toxic effects; and (7) the development of short-term neuro-behavioral toxicity assays.
